My DS is 15 months old. Arrangements in place is for his dad to have him 3 x a week for 2 hours. And every 3rd Sunday for 5 hours. His dad works and my son goes to bed at 7 so there’s a small window of time in the week anyway. My ex partner chose these times and days but is now saying he wants to change it and it’s only been in place for a week! We previously had to cut down the times because he was being such a let down. Please tell me AIBU????? (My son is breastfed so we both agree no overnights at the min)
